66.67% or 2/3

Step-by-step explanation:

He put 1/3 of his sports books on the shelf. Ignore the 1/4 and focus on how much space the sports books are not taking up which would be 1-1/3=2/3 or 66.67%.

The amount Diego charges to detail an SUV is proportional to the time it takes him to detail the vehicle. Diego charges $37.50 t

prisoha [69]

Answer:

$d = 15h$

Step-by-step explanation:

Given

$Charges\ \alpha\ Time$

Represent charges with d and time with h

So:

$d = \$37.50$ when $t = 2.50\ hours$

Required

Determine the formula

$Charges\ \alpha\ Time$

In other words,

$d\ \alpha\ h$

Convert to an equation

$d = k * h$

Where

k = constant of proportion

Substitute values for Charges and Time

$37.50 = k * 2.5$

Solve for k

$k = 37.50/2.50$

$k = 15$

Substitute 15 for k in $d = k * h$

$d = 15 * h$

$d = 15h$

The above formula models the situation

What is the value of |−44|?

julsineya [31]

Hey there!

Here is your answer:

The proper answer to this question is "44" .

Reason:

Think of it like this:

| | <---- This represents a car wash

When you add a positive or negative number in between the lines it represents a car going through the car wash.

So if...

|-44| (goes through the car wash)=44
|44| (goes through the care wash)=44

Therefore it would equal 44.

If you need anymore help feel free to ask me!

Hope this helps!
